Understanding Fall Protection Requirements
A suitable question at this juncture. Many people have doubts about fall protection requirements. Most of them seek shelter under regulations. Of course, regulations are helpful, and a few areas cannot be managed without stringent statutes. My answers are with a broader perspective and in an industrial context.
A person can fall on the same level or from any height. We consider falls from heights seriously, though falling on the same level cannot be taken lightly. Here, fall protection needed at height is considered.
We can protect a person from falling to a lower level by:
- Fall protection system
- Fall arrest system
Examples of fall protection systems are parapets on a terrace, guardrails, barricading, or covering of openings at height, and so on. Examples of fall arrest systems are full-body harnesses with lanyards, positioning devices, nets, and so on.
Determining the Required Height for Fall Protection
Here the question is: at what height do we need fall protection? The answer is any height from where a person can fall and sustain an injury. This answer is not satisfactory. Here we have to analyze: a fall from what height can cause severe injury or fatality? A fall from 0.3 meters to 1.2 meters seldom results in fatality. However, falls from a height of 1.8 meters mostly result in severe head injuries and fatality. With the above, one can easily conclude that over 1.8 meters, we need fall protection, and it is as simple as that.
Now the regulations vary from country to country. In India, it is over 3 meters. In the USA, as per OSHA, for general industry, it is over 1.2 meters, and in construction, 1.8 meters.
Safety Harness Usage
Coming back to your posting, please note that the use of a safety belt is not advised, and it is better to avoid it. We have to advise the use of a full-body harness only, and there are solid reasons behind it. At what height can you work without a safety harness? The answer is: at any height where another means of fall protection system is provided!
For using a safety harness with a 1.8-meter lanyard, the minimum free fall distance should be +4 meters. However, with a shock-absorbing lanyard, the minimum free fall distance should be 6 meters, without which the use of a safety harness is of no use.
Hope you make it.
